DELIVERY MECHANISM FOR PRINTING-PRESS ES.

SPECIFICATION forming part (if Letters ratent No. 270,267, dated January9, 1883.

' Application filed June 24,1881. (No model.)

i I do hereby declare that the following specification, when taken inconnection with thedrawings which accompany and form part of the same,isa description of my invention, s'ufficient to enable those skilled inthe art to practice it. p

My invention relates to improvements in the means or mechanism fordelivering sheets of paper from cylinder-presses after the same havebeen printed; and the object of my invention is to provide a positivemeans for the delivery of such sheets of paper from theimpressioncylinder. I attain this object by the mechan ism illustratedin the accompanying drawings, in which Figure 1 is a side elevation ofthe machine. Fig. 2 is a longitudinalsectional elevation there of. Fig.3 is a plan view thereof. Fig. atis a top view of one of thedelivery-grippers as atfixed to one of the belts. Fig. 5 is a sectionalside elevation of one of the delivery-grippers.

0n the frame A is mounted the impressioncylinder B in the usual manner,said impression-cylinder being provided with grippers operated bysuitable mechanism, and so adjusted that they take their hold on thesheet at the .able bearings and parallel with the axis of theimpression-cylinder. Upon the shaft is secured a spur-gear, E, which.meshes with the driving-gear F on the shaft of the impressioncylinder,and by means of these gears the said shaft D, with its attachments, isrotated in a direction opposite to that in which the impression-cylinderturns. The operation of the adj ustable spur-gear E is such that when itis desired to delive r a sheet of paper with a, wide margin theset-screw of the adjustable spurgear E is loosened, which releases thegib-key and allows the shaft to which the delivery-pulleys are attachedto be turned back to a sufflcient distance, so that the grippers on thedelivery-belts will take the edge of the sheet as it is delivered by thegrippers of the impression-cylinder, and vice versa if the margin isnarrow. The set-screw is then tightened, and the delivery mechanism isready for operation. This method of adjustment of the spur-gear wheel Ecircumferentially on the shaft to which the pulleys of thedelivery-cylinder are attached enables themachine to be adjusted readilyto deliver any desired width of margin. The hubs of the pulleysor-wheels composing said delivery-cylinder are provided with setscrews,by means of which said pulleys are secured longitudinally on the shaftD. This arrangement enables the said pulleys or wheels to be set andsecured at any desired point on the shaft, so as to properly deliver anywidth said flier. The fly-fin gers of the sheet-flierH are held by meansof adjustable clamps, furnished with set-screwsforsecuriu g them to thegrooved stock or shaft, as shown in Fig.3 of the drawlngs.

I are endless delivery-belts, carrying independent grippers K, saidgrippers being provided with cranks and springs for opening and closingthe same, as shown in Figs. 4: and 5. At the proper time the saidgrippers are opened by their cranks passingover suitably-arranged cams Nand O, and are automatically closed by their springs. Thesedelivery-belts are also provided with a series of buttons, L, secured totheir surfaces, said buttons having points on which the sheet restswhile being delivered .to support it above the surface of the belt andgrippers on the impression-cylinder, and 0 are 1. In acylinder,printing-press,thecombina- 25 similarly-adjustable cams foropening the delivery-grippers and releasing the sheet at the propertime, in order that the sheet-flier may deposit it on thedelivery-tal'ile.

The operation of this improved machine is such that the sheet is fedinto the press in the usual way. The grippers ofthe impression-cylindertake the sheet, hold it during the operation of printing, and at theproper time deliver it to the independent grippers K, affixed to thedelivery-belts, which instantly close upon it and carry it over thedelivery-cylinder to and over the sheet-flier, when the cams 0 open thegrippers, thereby releasing the sheet, which is deposited by the flieron the receiving-table. Owing to the positive action of this deliverymechanism, there is no possibility of the sheet slipping on the belts,and it is also kept entirely above the surface of the belts by theaction of the buttons L, thereby removing all possibility of smutting.

WhatI claim as myinvention, and desire to secure by Letters Patent, is-

tion of an impression-cylinder provided with grippers, adelivery-cylinder, consisting of a series of adjustable recessed flangedwheels, a series of belts carrying grippers, chucks, and buttons orrests, a second series of flanged and recessed wheels or pulleysarranged in close proximity to asheet-flier, so that the belts pass ingover the two series of pulleys are above the plane of rest of thesheet-flier, and a sheetfiier, all arranged and combined as specified.

2. In a cylinder printing-press, the combination of a sheet-flier, areceiving-cylinder provided with belts carrying grippers and buttons orrests, and an impressioncylinder provided with grippers, butwithouttapes, all arranged and combined as specified.'
